PE/PP/UPE Plastic Bearings (Anti-Acid and Anti-Alkali Bearings)

HDPE,PP, and the UPE materials have proves can be used for a relativel weak acid-base cross environment(30% Cucl2 solution 30% NaoH solution test OK)it applies to most of the number of acid / base / salt / solvent / oil / gas and seawater corrosion environment. With general plastic bearings, oil-free self-lubricating, anti-mangenric electrical insulation performance, but lower mechanical strength, easily deformed, it is such resistance to scid-base plastic bearings are not used for larger loads and higher speed, in order to overcome this kind of acid-fast The drawback of alkali plastic bearings. In comparision, the use of UPE materials have better strength, low friction characteristics and low-temperature characteristics(minimum to -150℃)inside and outside the ring material uses of HDPE, PP or the UPE, ball glass ball,stainless steel balls or ceramic.

F A Q

1. Why do the bearings I received have shaking?

The clearance of the bearing is related to the play. The default is the standard C0 clearance, which is usually 3-18um. The corresponding principle is shown in the figure below. If you don't need to shake, please choose C2 small clearance bearing. If you have any questions, please contact us before purchasing.

2. What is the accuracy of ABEC-1?

ABEC is the American ANSI standard. The corresponding German DIN standard and international ISO standard are as follows:
